[0002] Shunting winches are used for loading and unloading goods at railway train transportation sites such as coal mines, coal washing plants, power plants, cement plants, and ports to dispatch trains. They are composed of several components, including an electric motor, coupling, brake, reducer, and friction wheel.

[0003] The outer wall of the wire rope on the existing coal mine shunting winch is prone to dust and other impurities or water stains, which can easily lead to damage to the wire rope.

[0004] To address the aforementioned problems, this application proposes a shunting winch for coal mines. Utility Model Content

[0005] In order to solve the problem that dust and other impurities or water stains easily adhere to the outer wall of the wire rope on the existing shunting winch used in coal mines, the purpose of this utility model is to provide a shunting winch for coal mines.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a shunting winch for coal mines, including a shunting winch body, a winch for cooperation connected to one end of the shunting winch body, and a protective mechanism for cooperation with the winch on the shunting winch body, and a limiting mechanism for cooperation on the protective mechanism.

[0007] The protective mechanism includes an outer cylinder, which is bolted to the main body of the shunting winch and can be fixedly sleeved on the outside of the winch. An arc-shaped groove for matching is formed through the outer cylinder, and a side plate is fixedly connected to one end of the outer cylinder. Symmetrically arranged rotating rods are rotatably inserted into one end of the side plate, and guide wheels that mate with the arc-shaped groove are rotatably sleeved on the rotating rods. Symmetrically arranged rotating holes are formed through one end of the side plate, and the rotating rods are rotatably inserted into the rotating holes. A motor is fixedly installed on one side of the side plate, and the output end of the motor rotatably passes through the side plate and is fixedly connected to its end. There is a side rod, and a fan blade is fixedly sleeved at the end of the side rod. A gear one is fixedly sleeved at the end of the motor output far away from the side rod. A symmetrically distributed rotating shaft is rotatably inserted at the other end of the side plate, and a meshing gear two is fixedly sleeved on the rotating shaft. A clamping plate is fixedly connected to the end of the rotating shaft, and a brush tube is slidably sleeved on the clamping plate. A slot is opened through the middle of the brush tube, and the clamping plate can be slidably inserted into the slot. The inner diameter of the slot is the same as the outer diameter of the clamping plate. A gear three is fixedly sleeved on the rotating shaft near the top of the side plate, and gear three meshes with gear one.

[0008] Preferably, the limiting mechanism includes a frame with a through groove and an inner groove for cooperation, and a locking plate can be slidably inserted into the through groove. A pull rod is slidably inserted into the frame, and an insert block is fixedly connected to the end of the pull rod. A sliding hole communicating with the inner groove is opened through the frame, and the pull rod is slidably inserted into the sliding hole. A grip ball is fixedly connected to the end of the pull rod away from the insert block, and the outer wall of the grip ball is covered with a layer of anti-slip texture. The insert block can be slidably inserted into the inner groove, and a spring is fixedly installed on one side of the insert block. The end of the spring is fixedly connected to the inner wall of the inner groove. A slot is opened at the end of the locking plate, and the insert block can be slidably inserted into the slot. The outer diameter of the insert block is the same as the inner diameter of the slot.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. The use of the shielding mechanism can drive the fan blades to rotate, and at the same time drive the two brush cylinders to rotate in reverse synchronously. This can effectively clean the dust and other impurities attached to the outer wall of the wire rope to be wound, and after the wire rope is dried, it can be covered and stored. This can provide good protection for the wound wire rope and prevent it from being damaged due to a large amount of dust and other impurities or water stains.

[0011] 2. The use of the limit mechanism facilitates the pulling and resetting of the lever, which in turn facilitates the pulling and resetting of the insert, and further facilitates the insertion and separation of the insert and slot, thus facilitating the replacement of the brush cylinder and ensuring the normal use of the shielding mechanism.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figures 1-5 As shown, this utility model provides a shunting winch for coal mines, including a shunting winch body 1, a winch 2 rotatably connected to one end of the shunting winch body 1, and a protective mechanism 3 that works with the winch 2 on the shunting winch body 1, and a limiting mechanism 4 that works with the protective mechanism 3.

[0021] The protective mechanism 3 includes an outer cylinder 31, which is bolted to the main body 1 of the shunting winch. The outer cylinder 31 can be fixedly sleeved on the outside of the winch 2. An arc-shaped groove 32 for matching is opened through the outer cylinder 31, and a side plate 33 is fixedly connected to one end of the outer cylinder 31. A symmetrically arranged rotating rod 34 is rotatably inserted into one end of the side plate 33, and a guide wheel 35 that matches the arc-shaped groove 32 is rotatably sleeved on the rotating rod 34. A symmetrically arranged rotating hole 316 is opened through one end of the side plate 33, and the rotating rod 34 is rotatably inserted into the rotating hole 316. The rotating hole 316 provides a guarantee for the stable rotation of the rotating rod 34. A motor 36 is fixedly installed on one side of the side plate 33, and the output end of the motor 36 rotatably passes through the side plate 33 and is fixedly connected to a side rod 37 at its end. A fan blade 38 is fixedly sleeved at the end of the side plate 37, and a gear 39 is fixedly sleeved at the end of the motor 36 away from the side rod 37. A symmetrically distributed rotating shaft 310 is rotatably inserted at the other end of the side plate 33, and a meshing gear 311 is fixedly sleeved on the rotating shaft 310. A retaining plate 312 is fixedly connected to the end of the rotating shaft 310, and a brush cylinder 313 is slidably sleeved on the retaining plate 312. A retaining groove 317 is opened through the middle of the brush cylinder 313, and the retaining plate 312 can be slidably inserted into the retaining groove 317. The inner diameter of the retaining groove 317 is the same as the outer diameter of the retaining plate 312, thereby ensuring the stable insertion of the retaining plate 312 and the brush cylinder 313. A gear 314 is fixedly sleeved on the rotating shaft 310 near the top of the side plate 33, and the gear 314 meshes with the gear 39.

[0022] By adopting the above technical solution, during use, the end of the wire rope wound on the winch 2 passes through the arc-shaped groove 32 and between the two guide wheels 35, and then the end of the wire rope passes between the corresponding two brush cylinders 313. This allows the motor 36 to be started during the wire rope winding, thereby driving the side rod 37 and gear 1 39 to rotate synchronously, further driving the fan blade 38 to rotate. At the same time, gear 1 39 will drive gear 314 to rotate synchronously in reverse, thereby driving the corresponding rotating shaft 310 to rotate synchronously in reverse, and further driving the corresponding gear 2 311 and... The synchronous reverse rotation of the clamping plate 312 further drives the corresponding brush cylinder 313 to rotate synchronously, thereby driving the other gear 311 to rotate synchronously. This, in turn, drives the corresponding brush cylinder 313 to rotate synchronously through the corresponding clamping plate 312, and further enables the two brush cylinders 313 to rotate synchronously. This effectively cleans the dust and other impurities adhering to the outer wall of the wire rope to be wound, and after the wire rope is air-dried, it is covered and stored. This provides good protection for the wound wire rope and prevents it from being damaged by a large amount of dust, impurities, or water stains.

[0023] The limiting mechanism 4 includes a frame 41, on which a through groove 42 and an inner groove 43 are provided for cooperation. The locking plate 312 can be slidably inserted into the through groove 42. A pull rod 44 is slidably inserted into the frame 41, and an insert block 45 is fixedly connected to the end of the pull rod 44. A sliding hole 47 communicating with the inner groove 43 is provided through the frame 41, and the pull rod 44 is slidably inserted into the sliding hole 47. A ball grip 48 is fixedly connected to the end of the pull rod 44 away from the insert block 45, and the outer wall of the ball grip 48 is covered with... A layer of anti-slip texture is provided, which can increase friction and facilitate operation. The insert 45 can be slidably inserted into the inner groove 43, and a spring 46 is fixedly installed on one side of the insert 45. The end of the spring 46 is fixedly connected to the inner wall of the inner groove 43. The end of the card plate 312 has a slot 315, and the insert 45 can be slidably inserted into the slot 315. The outer diameter of the insert 45 is the same as the inner diameter of the slot 315, thereby ensuring the stability of the insertion of the insert 45 and the slot 315.

[0024] By adopting the above technical solution, during subsequent use, the user can pull the ball 48 away from the frame 41, thereby driving the corresponding pull rod 44 and the insert block 45 to move and squeeze the corresponding spring 46. When the insert block 45 is completely separated from the corresponding slot 315, the corresponding frame 41 can be removed. Then, the corresponding brush cylinder 313 can be removed and replaced. After replacement, the corresponding frame 41 can be reset and fixed.

[0025] Working principle: During use, the end of the wire rope wound on the winch 2 passes through the arc-shaped groove 32 and between the two guide wheels 35. Then, the end of the wire rope passes between the corresponding two brush cylinders 313. This allows the motor 36 to be started during the wire rope winding, which in turn drives the side rod 37 and gear 1 39 to rotate synchronously, further driving the fan blade 38 to rotate. At the same time, gear 1 39 drives gear 314 to rotate synchronously in reverse, which in turn drives the corresponding rotating shaft 310 to rotate synchronously in reverse, thereby driving the corresponding gear 2 311 and the clamping plate 3. The synchronous reverse rotation of the 12 brush cylinders further drives the corresponding brush cylinder 313 to rotate synchronously, which in turn drives another gear 311 to rotate synchronously. This, in turn, drives the corresponding brush cylinder 313 to rotate synchronously through the corresponding clamping plate 312. This allows the two brush cylinders 313 to rotate synchronously, effectively cleaning the dust and other impurities adhering to the outer wall of the wire rope to be wound. After the wire rope is dried, it is covered and stored, thus providing good protection for the wound wire rope and preventing it from being damaged due to the adhering of a large amount of dust and other impurities or water stains.

[0026] In addition, during subsequent use, the user can pull the ball 48 away from the frame 41, thereby moving the corresponding lever 44 and the insert 45 and squeezing the corresponding spring 46. When the insert 45 is completely separated from the corresponding slot 315, the corresponding frame 41 can be removed. Then, the corresponding brush tube 313 can be removed and replaced. After replacement, the corresponding frame 41 can be reset and fixed.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
